Firefighters battle brusher in Azusa

Firefighters are fighting a 2-alarm brush fire in a riverbed next to Encanto Park in Duarte, officials said.

The blaze was reported about at 4:05 p.m. near the park, located at 800 Encanto Parkway, and was reported to be at 1 acre just prior to 5 p.m., Los Angeles County Fire Department dispatchers said.

About 100 personnel were battling the fire, which officials said was burning in "medium brush."

No structured were immediately threatened, however firefighters were placed in between the fire and nearby homes as a precaution.

Steep terrain, high winds and the fire's proximity to buildings promted the heavy response to the fire, officials said.

A cause was not known.
